Abstract

In a process for perforating smooth, skinned surfaces of open cell plastic foams, an extruded plastic foam sheet (16) is heated, vacuum formed, cooled and one of the facing skins (12,13) is perforated by needles (4). Process equipment has a tool part (11) with fixed or movable needle (4) in a matrix pattern. Needle tips (18) extend above the tool (11) surface during perforation. Pref. in process variations (i) the sheet (16) may be coextruded with a coloured or uncoloured facing layer of similar or dissimilar material to the sheet (16) before vacuum forming and perforating or (ii) the plastic sheet (16) itself is extruded without facing layers. Needling may be performed before or after sheet (16) thermoforming. Needles (4) may oscillate backwards and forwards or are fixed in a tool block which is moved towards the sheet (16) supported on a backing plate. In an alternative process perforating is effected by needles on a rotating roller, prior to thermoforming. A container can be perforated in both sidewalls and base by needles moving perpendicular to the respective surfaces. In a further alternative process the thermoformed prod. is moved to a perforating station and pressed against a fixed plate by moveable perforating blocks. Needles fixed to a plate are then raised to perforate the prod. resting on the perforating block.
